xmlsec.tree#

Common XML utility functions

xmlsec.tree.add_ids(node, ids) → None#

Registers ids as ids used below node. ids is a sequence of attribute names used as XML ids in the subtree rooted at node. A call to add_ids() may be necessary to make known which attributes contain XML ids. This is the case, if a transform references an id via XPointer or a self document uri and the id inkey_data_formation is not available by other means (e.g. an associated DTD or XML schema).
